METHOD OF MAKING GOTTONBATTING.

Original application filed March 24, 1887, Serial No. 232,293. Divided and this application lcd November 29, 1887. Serial No.

To all whom it may concern:

Be it known that we, EDWARD WALKER and DAVID WILLIAMs, citizens of the United States, residing at Cohoes, in the county of Albany and State of New York, have invented certain new and useful Improvements in Methods of Making Cotton-Batting; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and iigures of reference marked thereon, which form apart of this specification.

lOur invention relates to cotton-batting, and has for its object to produce a bat of increased strength and durability composed of a series of layers the bers of which lie obliquely to the length of the web, the web having a continuous unbroken surface; secondly, to produce such a bat in which the bers, besides lying obliquely to the length of the web, will also have the bers of each layer lying obliquely across the fibers of the layer upon which it rests; also, to form such a bat folded upon itself lengthwise thereof.

To the formation of such a bat, the invention consists in the method hereinafter parA ticularly described and claimed, reference be ing had to the accompanying drawings as an illustration of the best means for carrying out the invention, in Which-- Figure l is a perspective view of the delivery-rolls of three cards and apart of the trough for the traveling apron. Fig. 2 is a perspective view of a fragment of the batting with a portion of the layers broken away.

In the drawings, the letters A, A2, and A3 designate parts of aseries of carding-machines of any approved general construction and operating in the ordinary Well-known Way, a more particular description thereof being un4- necessary. Ve have shown parts of three carding-machines; but the number may be varied. These cards have the delivering-rolls B arranged so that instead of discharging the cotton directly to the front of the card in the line of travel of the cards they deliver at an oblique angle or other angle thereto, so that when a series of machines is arranged to deliver and lay the cotton in layers the bers of thelayers will lie across each other instead of parallel with the length of the web or bat. To illustrate, it will be seen on reference to the drawings that ,the card A3 delivers the cot= ton C onto the traveling apron D at an oblique angle to the-line of travel of the apron, with the vline of inclination or Obliquity extending from theinner to the outer edge of the apron in the direction of the line of travel of the apron, which causes the length of the ber to lie obliquely across the apron. The card A2 delivers upon the apron D with the line of Obliquity extending from the outer to the in ner edge of the apron in the direction of the line of travel of the apron, which causes the ber to lie across the apron in the opposite direction to the bers of the first layer.. The

card A2 delivers in the same direction as card A3, which causes the bers of its layers to lie across the apron in the same line of Obliquity as those of the rst layer and across the middle layer in the opposite direction to the line of delivery of said layer. The consequence is that the bat is formed of layers of bers which cross each other with the effect of making a smooth and stronger web.

It willbe observed,too,thatthe endless apron D travels in the trough F at an angle-say a right angleto the front of the cards, which permits the cotton to be formed in layers, the cotton from card A3 being the rst laid upon the apron, then the cotton from A2 being laid upon it, and afterward cotton from card A laid upon that from A2. This arrangement permits the bat to be formed in layers in a simple and expeditious manner, and by moving the apron faster or slower, as desired, the bat will be formed thinner or thicker, as Wanted.

Another advantage in having the apron travel in front of the cards, as described, and of forming the bat or web in layers, is that the nest or best cotton can be used for the outside of the bat or web and not so good a grade of stock for the inner layers, so that the appearance and advantage of having a bat with the best stock on the outside, or side exposed to Wear, is obtained at a saving of stock and eX pense. This best stock will be on both sides of the web, because the web will be folded by IOO It will be observed that by delivering the4 v sliver or layer from the card onto a traveling layer obliquely to the line of travel of the layer onto which it is fed one layer is made to overlie the other in a practically continuous unbroken surface, with the fibers of the layer lying obliquely to the length of the web.

It will also bc observed that by feeding several layers one upon the other, with one layer fed in an opposite direction to another and the several layers obliquely to their line of travel, the fibers of the layers not only extend obliquely to the length of the web, but that also the fibers of one layer lie. obliquely across the fibers of another layer, so that still greater strength is obtained. By folding the web, formed as above described, upon itself lengthwise of the web, as described, there is obtained not only a betterfinished surface, but still further strength is added thereto.

We have illustrated and described parts of certain mechanism for carrying out the method; but no claim is4 made herein to mechanism, as the same forms the subject of another pending application of ours for the mechanism, filed March 2i, 1887, Serial No. 232,293, of which application this is a division and a continuation; and while we have referred to mechanism suitable for carrying out the method, still the invention is not dependent thereon, as the layers can be moved and fed as described by hand.

Having described our invention and set forth its merits, what we claim isl. The method of forming cotton-batting which consists in placing a fleece or layer of cotton upon a traveling surface, and then applying to said first layer as it moves with the traveling surface, in a single continuous unbroken layer extending lengthwise of the first Alayer, a second layer or fleece fed obliquely to the line of travel of the moving surface, and also obliquely to its own width, substantially as described.

2. The' method of forming cotton-batting which consists in .placing a fleece or layer of cotton upon a traveling Surface, then applying to said first layer as it moves with the traveling surface, in a single continuous unbroken layer extending lengthwise of the first layer, a second layer or fleece fed obliquely to the line of travel of the moving surface, and also obliquely to its own width, and afterward folding the web so formed upon itself lengthwise thereof, substantially as described.

3. The method of forming cotton batting which consists in placing a fleece or layer ot' cotton upon a traveling apron, and then applying to said rst layer as it moves with the traveling surface, in continuous unbroken layers extending lengthwise of the first layer, a series of other layers fed in opposite directions to each other, and one upon the other, and each obliquely to the line ot' travel of the moving surface, and also obliquely to its own width, substantially asand for the purposes described.

In testimony whereof we affix our signatures in presence of two witnesses.
